Experiments in the Mont Terri Rock Laboratory

The geological conditions in the Mont Terri Rock Laboratory include both fractured and undisturbed areas of rock and offer ideal conditions for a wide range of experiments. Today, the focus is on the performance and safety of the engineered and geological barriers of a deep repository. Projects at the Laboratory are investigating disposal concepts on a 1:1 scale. A controlled zone allows radionuclides to be used to test models of the transport of radioactive substances in the rock.

 

The current programme consists of a total of 30 different experiments, many of which are long-term projects extending over several research phases. The project partners hold regular meetings to discuss results and to consider the initiation and financing of new experiments.
